Walz urging Cliffs, U.S. Steel to work together

Hibtac, in particular, is facing a limited mine life. Cliffs is the majority owner there.

In the letter, Walz said Minntac has reliable reserves available for the immediate future, but has expressed interest in securing leases for additional high quality ore that would solidify the long-term options for the mine. U.S. Steel owns Minntac.

The letters says he looks forward to engaging in discussions to lay the groundwork for the continued success of both the mines.
